I just got back from a quick trip to Santa Cruz
Island with a couple of buddies, and have some questions about how hot water
heaters work. I understand that when you run your engine
it will heat water
inside the heater, and I also get that you can power it with electricity if desired. However, on this trip, we seemed to always have hot water available, even without running the main engine
, or having the switch on for the inverter
. So how long does a 6 gallon water heater stay warm? Overnight? For 24 hours? Doesn't seem likely. So maybe my hot water heater is wired to always be on. It would certainly help explain my large battery
drain while cruising.
I will troubleshoot the circuit this weekend to see what's what.
All suggestions are welcome.
